Example Crashed After Running

[lyce90]

Hi,

1. I downloaded the git repository,
2. edit the Podfile at Example Folder to the following:

platform :ios, '7.0'
target 'ipjsystest' do
  use_frameworks!
    pod 'pjsip'
end

3. Run pod Install
4. Changed the Bundle versions string, short to 0.9.0
5. Build and Run

The built was successful but after the simulator ran, it immediately crashed with the following message. Did I do anything wrong?

@lyce90 Can you take your time and use the issue template or at least format your code properly, please?

[lyce90]

@welljsjs My apologies, I have reformatted the code.

[welljsjs]

Thanks. Also, the examples are a little out of date I think.

I'd recommend having a look at this basic example: https://www.pjsip.org/pjsip/docs/html/page_pjsip_sample_simple_pjsuaua_c.htm

That should fulfill your needs at first. It's also the shortest example.

I am not sure whether the examples are actually still supposed to work. I wouldn't rely on them though.
